DensoSK20HR11- IRIDIUM PLATINUM power pack Spark Plugs - # 3421-4 PCS * NEW *

Perfect factory replacement plugs without having to gap them. No issues at all. Perfect fit. Easy to install. Long lasting.

OEM for a 2014 Toyota Tacoma 2.7 L, long life and well made sparkplug.

When you get good products every time you trust you'll get the right stuff next time you need something. I prefer using OEM so I purchase the good stuff when it is affordable.

These bad boys fitted just right and made the car perform how it should.

Just like the Denso coil-overs I purchased from Amazon; these are OEM parts. They just do not have Toyota stamped on them. They last about 80,000-100,000 miles. I changed my original plugs on my 2007 Tundra at 90,000 miles and got 100, 000 out of this last set. I was starting to have poor fuel milage and acceleration problems. I highly recommend these plugs and if you have high milage, I recommend changing your coil-overs.

Fits and working out great. Good buy.

I did not adjust anything, just swapped these on my extended cab 06 Tacoma. Engine feels smoother and more responsive. Did not affect gas mileage much. I reset the "trip 1" every time I fill up the tank. The next time I fill up, I divide those miles into the gallons I bought, then reset; normally got between 23.0 to 23.5 miles/gallon. If it drops under 22.5, replace the engine air filter; that fixed it.

Great plugs
